Does anyone know what OID I would poll to get the temperature of the Arris C3?

Thanks,

Can anyone advice me on what a fair cost would be for a Residential and Business line.

Is is cheaper to DIY or outsource. And if you Outsource whats fair price to pay.

Hi Group

I have a BSR2K and I want to change DS modulation from 64qam to 256qam to increase throughput. Is there any chance cable modems go offline when changing modulation? Issues related with this? I know in US modulation change, the SignalQuality goes down but I think is not the same in DS.

Thanks in advanced.

Hi!!

I have a problem, i want to make nat using Motorola BSR 1000, and i don´t found nat function in the IOS, and i want to know if it is possible in that CMTS ???

PD: i want to make nat using a pool of public ip addresses using that Motorola BSR.

Thanks.

Hi All,

i've been lurking the forum for a while and it helped me a lot al ready!
i got the whole system online including MTA's!

But now i want to split up the CPE network to different subnets, so this can be filtered by a transparant firewall.
e.g.

CM 1 - ip 10.20.0.5\24
CPE 1 - ip 172.16.0.10\24
CM 2 - ip 10.20.0.6\24
CPE 2 - ip 172.16.10.10\24

Provisioning :
Linux Debian distro
DHCP ( 2 pools, 1 for CM, 2 (or more) for CPE)
TFTPD
DNS
NNTP
MYSQL (DB with mac address + ip address CM network) --> managing our static hosts.conf for provisioning the CM's
+/- 300 CM

I think I mentioned before, I'm new in this.. so sorry if i bother too much.
and thanks if you understand me.
im very interesting in learn everything I can in this environment.

I recently got interested in estimate the consumption of bandwidth.
how could i do this...

i know how much total bandwith is generated monitoring the internet router directly.
Also i can generate graphic with mrtg tool.
but i cant know how that traffic is distributed in the cable modems.

example:
Total traffic was 1460kbps 2:00 pm
if I have only 3 cable modem connected

Hi Group,

I'm trying to understand how to calculate the Max-Burst-Size in the CM-configfile.
For that I took some specification RFI,DRFI,DVB and some cisco-pages and what
I could find in the web.

So what I figured out is the way to calculate the upstream-max-burst-size:

Assuming Modulation is 16-qam and Minislotsize 4 (Symbolrate=64)
= 4 (Bits_per_Symbol) * 64 (Symbol_Rate) = 256 (Bit) / 8 = 32 (Byte)
= 255 (max_minislots) * 32 (minislotsize_in_byte) = 8160 (Max_Burst_Size)

Assuming Modulation is 64-qam and Minislotsize 4 (Symbolrate=64)

Hi,
Fairly new around here, but I've been performing tests on our mini CMTS for a while, using a linux DHCP/TFTP server.
I need to create some new test scenarios, where I serve different CM config files to the various modems.
I have a batch of Hitron, Motorola and Castlenet Modems on the system, and I want to give them each type a different config file in the dhcp.conf
How do I go about this? I currently use a symbolic link (cm.0) to the CM config file on the TFTP server, which works fine.
essentially, I want to use cm.0, cm.1, cm.2 for the modem groups.

current config file:

Can someone explain what i have to do to make a eMTA work.
im using Arris TM602/G115 eMTA.
Like a Cable Modems works fine, but im unable to make the phone outputs work.

i dont have documentations of this.
attached i add the cable modem interfase status.

A wanted to shift enduser registration to the customers.
To protect our customer I've redacted some information from this example.

We decided to use reserved scope for registration.
a access-list that blokeds that scope from internet acces is in affect and 2 web server take care of registration.

First web server 10.127.0.15 will reply with "Location: http://register.client.com/" to any request.
Secound web server 10.127.0.13 is a LAMP installation.
A script will add static outside address to the dhcpd.conf file after registration.
